Made during WWII, this color film shows the men of the Coast Guard in operation in the Atlantic. Guardsmen man and command various support vessels and transports. Their cutters serve as Navy warships. Anti-submarine patrol is an important duty, and we see PBY flying boats, cutters and destroyers fending off enemy subs. As a seaborne invasion nears, USCG personnel and the men of the Merchant Marine rush men and supplies to the beach in LCIs and LSTs. The film clearly demonstrates the enormous role played by the Coast Guard and Merchant Marine in World War II. Also featured in this film is beautiful Kodachrome footage of aircraft carrier operations.
